block: Add child_of_bds
Any current user of child_file, child_format, and child_backing can and
should use this generic BdrvChildClass instead, as it can handle all of
these cases. However, to be able to do so, the users must pass the
appropriate BdrvChildRole when the child is created/attached. (The
following commits will take care of that.)
